Title: Centrifugal desalting method
Inventor: FUJIWARA KIYOSHI
IPC: C10G31/10
Filed: 1978-05-19
Abstract: PURPOSE: To desalt raw oil or heavy oil easily, charging a centrifugal extractor with a mixt. of raw material oil and water having been used for washing the oil as the light liq., and a small amount of fresh water as the heavy liq. in order to make both the liqs. contact with each other countercurrently.  
     CONSTITUTION: Raw material oil 1 is mixed with salt-contg. recycle water 20 having been used for washing, and the mixt. is heated in a preheater 19 to 40W 80°C, and is introduced through a mixing value 18 to a liq./liq. countercurrent centrifugal extractor 17 by way of a light liq. inlet side (the outer periphery side of the rotor). Simultaneously, fresh water 9 in an amount 1W5% based on the raw material oil is charged through a heavy liq. inlet side (the inner periphery of the rotor). The oil admitted from the light liq. side is separated from water at the outer periphery of the rotor and flows into the inner periphery side, and is washed with fresh water 9 admitted from heavy liq. side, it is then discharged as desalted oil 12'. Hereby, by use of only one centrifugal extractor, the salt content is decreased to 0.5 ppm at relatively low temp., without use of an emulsion breaker.

Gas containing atom to be implanted to the ion source 1 is introduced and formed to plasma; thereby, gas molecule is dispersed and ion containing atom to be implanted is generated. Hydrogen gas is introduced to an ion source 1 and ion species such as H<+> , H2 <+> , H3 <+> are generated when plasma is raised. When usual one atomic ion is used, H<+> alone is selected therefrom by a mass analyzer 2 and implanted to Si crystal.

Abstract: PURPOSE:To prevent the decrease in head output by providing additionally a cleaning member in the device and constituting the member that the member is contacted to the magnetic head as required and relative movement is caused between them so as to remove an affected layer produced on the surface of the magnetic head. CONSTITUTION:The cleaning operation is attained at any proper time, and in this case, a voltage is applied to a plunger 110 at first and a voltage is applied to a motor of a driving roller 102. Since a shaking lever 112 is moved to a position in solid lines by the operation of the plunger 110, a lapping tape 101 contacts a head 27A or 27B and raps the surface of the head by being moved clockwise so as to eliminate the affected layer of the surface of the head. Further, the step of the surface of the head caused by the sliding on a recording tape T is eliminated and the surface is smoothed by selecting the lapping tape. Thus, the decrease in the output of the magnetic head is prevented.
